When an IC card is passed over an external card reading and writing apparatus, the IC card starts communication with the card reading and writing apparatus via a wireless interface, so that a change in the internal state of the IC card is reported to an external device via an external wired interface or a dedicated control signal line, thus allowing a specific application to be enabled on the external device or allowing a controller to be powered on and activated. Alternatively, the controller is powered off and deactivated. Accordingly, processing according to the communication state between the IC card and the card reading and writing apparatus or the internal state of the IC card can be smoothly initiated.

IC chip and information processing terminal

Provided is a power receiving device including a power receiving coil which receives power supplied by electromagnetic waves, and a measurement coil which is disposed near the power receiving coil and measures an electromagnetic field.

Power receiving device, electric circuit, and power supply device

A power receiving coil and a measuring coil are in a power receiving device. The measuring coil is inductively coupled to the power receiving coil. Concentric turns of a wire in the measuring coil are around a common axis. Also around the common axis are concentric turns of a wire in the power receiving coil. At least one of the concentric turns of the wire in the measuring coil is closer to the common axis than each of the concentric turns of the wire in the power receiving coil. A power feeding device receives a control signal from the power receiving device. The control signal instructs the power feeding device to adjust a power level of an electromagnetic wave emission.

Power receiving device and power feeding system

A method for a communication device includes determining whether a first radio frequency (RF) signal at a level of at least a first predetermined field threshold is detected. The method also includes generating a second RF signal at a level of at least a second predetermined field threshold greater than the first predetermined field threshold, when the communication device receives an instruction to generate the second RF signal and the determining determines that the first RF signal at the level of at least the first predetermined field threshold is not detected. The method further includes receiving a load modulated RF signal in response to the second RF signal.

Communication system, communication apparatus and communication method

An application program relating to a process of an integrated circuit is stored in a virtual integrated circuit storage area server apparatus. Following a mutual authentication between the IC and the virtual storage area server apparatus through a portable communication function unit, the server apparatus executes the application program. Additionally, through the IC, the portable communication function unit, a wireless communication line, and a network, communicate with an IC_R/W apparatus and perform a process relating to a service in collaboration with each other.

Circuit device and a communication apparatus

Some embodiments of the invention provide a server apparatus, comprising: a control block comprising at least one processor; at least one data reception unit operable to receive a request to share a picture; at least one storage facility, storing programmed instructions for execution by the control block, the programmed instructions defining an image analysis engine operable to determine that the picture comprises an image of a person; and at least one data transmission unit operable to issue a request to the person, or someone associated with the person, to consent to sharing the image. Other embodiments provide a method, performed by at least one computer. The method comprises: (A) receiving a request to share a picture; (B) determining that the picture comprises an image of a person; and (C) requesting that the person, or someone associated with the person, consent to sharing the image.

Preserving user privacy

A power receiving device including: a power receiving coil configured to receive power when a power feeding device supplies the power via a magnetic field; an alternating-current power supply configured to apply an alternating voltage to the power receiving coil; and a foreign matter detecting section configured to generate an amount of change in impedance of the power receiving coil from a current induced in the power receiving coil to which the alternating voltage is applied and the alternating voltage, and detect foreign matter between the power receiving coil and the power feeding device on a basis of the amount of change.
